Battery

The battery is to be fixed to the inside of the enclosure using double sided scotch tape. The battery must have the following dimensions.

• 5mm thick
• 40mm Wide

The JST socket on the ESP32 Marauder accepts a female 2mm pitch 2-pin JST PH series connector.

I have chosen a 1500mah 504050 LiPo found here

Charging and Output

Battery charging, output, and boost is accomplished using an INJOINIC IP5306 I2C.
Notable features:

• Output over current, over voltage, short circuit protection
• Input overvoltage, overcharge, overdischarge, overcurrent discharge protection
• Standby power consumption is less than 100 µA
• Boost efficiency up to 92%
• Customizable I2C interface
• Output voltage 5V

The datasheet for the IP5306 can be found here.
